There are a lot of old fights that just cannot be watched today, because it wasnt taped or the footage dissapeared. What fights would you want to see the most, if you could get footage of it?(Also because a lot of the film is crap, you can include ones that exist but are really hard to appreciate because the quality is so bad).

For me its...
Greb vs Tunney 1, or any meaningful Greb fight for that matter
Locche vs Cervantes 1(more than just the last round)
